Faculty of Humanity and Economy, China University of Geosciences,Wuhan 430074, China;3.Department of Computational Science and Mathematics, Guilin University of Electronic Technology, Guilin 541004, China)In this paper, we study oscillatory properties of solutions to nonlinear impulsive hyperbolic partial differential equations with delay. It inverted the discussed impulsive delayed partial differential equations into impulsive delayed ordinary differential equations via the method of differential inequalities. Several sufficient criterias are established for oscillations of the solutions impulsive hyperbolic Robin boundary value problems. The results fully extend the oscillatory properties of impulsive differential equations to impulsive partial differential equations with delayed. It reflects the influence action of impulsive and delay in oscillations. The paper also showed that oscillatory properties of solutions to impulsive hyperbolic partial differential equations with delay have wide applications in such subjects as biology、medicine、engineering、chemistry and physics.hyperbolic equations; impulsive; oscillation
